To define a particular term: In an octagon the sum of the measures of the interior angles is ______

Expert Solution & Answer

Answer to Problem 43CUR

In an octagon the sum of the measures of the interior angles is 1080∘

Explanation of Solution

Given information:

In an octagon the sum of the measures of the interior angles is ______

The sum of the measures of the interior angles of a convex polygon with n sides is (n−2)×180

For octagon the value of n will be 8.

Hence the sum of interior angles is given by:

=(n−2)×180∘

=(8−2)×180∘

=6×180∘

=1080∘

The sum of the interior angles of octagon is =1080∘
